Electronic control unit with frequency converter for Wilo pumps. Sirio 3x230 is designed for motors (pumps) with three-phase power supply 3x230V (not for three-phase 3x400V!!!).

Application

Sirio 3x230 can be used with the following types of Wilo pumps:

• Domestic waterworks
• Submersible pumps for wells and boreholes
• Self-priming pumps

Functions of the control unit

The Wilo Sirio 3x230 control unit can be used when we need to take advantage of smooth pump speed regulation. Sirio 3x230 allows control of the output pressure within a very narrow regulation band, which leads to a reduction or complete elimination of the pressure tank on the discharge pipe. It also contributes to reducing energy consumption, noise, and overall extending the system's lifespan.

Features and benefits

• Maintains constant pressure in the system through speed regulation.
• Integrated motor overcurrent protection.
• Smooth start and stop.
• Dry run protection.
• Operational status indication via display and LED indicators.
• Option to set two pressure levels.
• Leakage sensor protects the pump from frequent starts.
• Easy and quick installation.
